The furnace protection is to stop the furnace with a furnace protection agent for metal surface protection. It is a film-forming corrosion inhibitor based on octadecylamine, which can promote the corrosion during corrosion. The hazard is particularly large, let's take a look at the scope of application of the shutdown protection agent.
The deactivated protective agent has the characteristics of good protection effect, convenient use and low price in the tens of thousands of deactivated boilers. It is especially suitable for the shutdown and maintenance of seasonal production and domestic boilers such as heating boilers and sugar food processing. 
Features:
Efficient : After using the boiler and equipment to put the protective agent, there is no signs of corrosion and rust on the metal surface within one year.
Convenient : the use of protective agent does not need to dry the boiler, nor does it need to be analyzed and inspected regularly. As long as the furnace water is drained to open the pores of the hole, a tray containing the protective agent is placed in the boiler header, and 3000-5000 grams per cubic space is placed. Then close the boiler and apply it once. This product is a powder white solid powder, non-toxic and non-combustible for transportation, storage and use.
Cheap : The protective agent is used to protect the boiler from the traditional dry and wet protection.
Protection principle:
The protective agent has strong water absorption, and the protective gas is released after water absorption, so that the boiler is filled with the gas, and the steel surface of the boiler is passivated to achieve a good protection effect.
Precautions:
1. If the water is discharged from the boiler after the water is discharged, the amount of the medicine will increase accordingly.
2. This product is harmless to the operation of the boiler, and only the container can be taken out when the boiler is restarted. 
Used in various types of medium and low pressure steam boilers, hot water boilers, flashers, steam generators, distilled water, heat exchangers, water cooling or water heating jackets and other heat exchange equipment to prevent fouling and scale removal.
It is used to supplement the feed water quality of medium and high pressure boilers to prevent scaling due to water treatment failure.
Descaling : The scale and sludge deposits that have been formed can be dispersed and discharged in the normal operation and maintenance of the equipment to restore the heat transfer surface to a clean state.
Economy : Eliminate the cost of cleaning and descaling and other various water treatment costs, so that heat exchange equipment such as boilers can maintain thermal efficiency and greatly reduce energy consumption costs.
Safety : Neutral maintenance, non-toxic, harmless and non-polluting, no corrosion damage to equipment. This product does not enter steam, and steam boilers such as food, wine, and life can also be used.
When using the shutdown protectant, be sure to add enough, otherwise you will not achieve the desired effect. When draining, all the sewage valves should be discharged. When stopping the furnace, the sewage valves should be fully opened, and the water slag should be cleaned with clean water to prevent blockage.
